The 25% figure has come from mipv who did the trial.

And I've already provided the link 8 posts back for the parent company specifications downloads

I'm sorry I can't provide any more info on specs than they have - I suggest you either contact them direct to get whatever you need or just go ahead and buy the cheapest Chinese panels you have found

My point was the link to their "leisure" site lists several advantages, such as low profile and reduced weight, which I wouldn't argue with. Then it goes into some distinctly wooly claims about being better at low light levels and at higher temperatures but gives no test results to support these claims.
If the performance was that good they should be shouting it from the rooftops. I can't see anything obvious in their downloads page about this.

When I asked these same questions I was given the link to the parent company downloads - have you actually looked at them?

See the last paragraph I added above while you were posting. Can you give a specific link to some test results? I've looked and nothing jumped out at me - but I am overdue a visit to the opticians.

Indeed you should, side by side same controller just different panels

This is my question with it. We re looking at £9k for 4kw Bipv as opposed to £4k with integrated conventional pv's and while I like the theory and I have seen it properly in action, I've not seen any examples that I would consider a meaningful comparison.

Looking at putting a Bipv panel on the mh means fitting a separate system which is costly and its the wrong time of year to give results unless they're really amazing..

If I was showing an "amazing new PV panel" I would have one rigged up side by side with the much inferior existing technology and then point them both at the sun, seems quite simple and dare I say even sensible to me.

I think I've found the controller for sale separately.



These could be an alternative.

An interesting read comparing the various solar panel technologies and marketing claims.

An interesting read indeed. At best in certain circumstances there might be a marginal advantage but in the real world there isn't anything to recommend them, particularly after taking into account the cost premium.

"The clear conclusion from this multi-year side by side test is that thin film modules do not outperform crystalline silicon modules."

Having stumbled across this thread whilst mulling over which way to go with solar installation I'm wondering if anyone who's been using Photonic Universe equipment can add anything on its longevity?

I got a 280w kit from them in 2017 via Amazon. Panel, MPPT charger and mounting hardware. I sold the van earlier this year. Didn't have any issues with the Photonic Universe stuff. We did about 30k miles, including 6 months in Europe where we were mostly off-grid, so relied on the solar a lot.

Ours is still working great at 4 years ish
